The father removed 3 of the children, claimed the daughter had run off to a cult and left these 3 kids on the doorstep as infants. He and his wife raised them. The remaining 3 kids that he said were "crybabies" were left in the dungeon with their mother (his daughter). One other child, a twin, supposedly died in infancy and incinerated it in a furnace.

I find it extremely difficult to believe this monster's wife did not suspect anything. Unless she, too, was abused by this control freak, a la Hedda Nussbaum. Also, the nice Austrians sentence murderers to only 20 years. The father is also now under investigation for an unsolved murder near property he owned.
